Age- and size-related changes in physiological characteristics and chemical composition of Acer pseudoplatanus and Fraxinus excelsior trees.
Forest growth is an important factor both economically and ecologically, and it follows a predictable trend with age. Generally, growth accelerates as canopies develop in young forests and declines substantially soon after maximum leaf area is attained. The causes of this decline are multiple and may be linked to age- or size-related processes, or both. Our objective was to determine the relati...
متن کاملSafety evaluation and nutritional composition of a Fraxinus excelsior seed extract, FraxiPure™.
A natural extract obtained from the seeds of Fraxinus excelsior L. (FraxiPure™) has been previously reported to reduce glycemia in animal models and in humans. The objective of this work was to evaluate the safety of FraxiPure™ at in vitro, in vivo and human levels. In addition, nutritional analyses revealed an extract high in carbohydrates, with minor levels of protein, dietary fiber, glucose ...
متن کاملCryopreservation of dormant European ash (Fraxinus excelsior) orthodox seeds.
We investigated the sensitivity of dormant Polish-provenance Fraxinus excelsior L. seeds to extreme desiccation and liquid nitrogen (LN, -196 degrees C). Germination and seedling emergence tests revealed that the critical water content (WC) of the desiccated seeds was 0.04-0.06 g H(2)O g(-1) dry mass, g g(-1) (0.04 g g(-1) in the germination test and 0.06 g g(-1) in the seedling emergence test)...

15 صفحه اولDifferences in Chemical Composition between Cow Colostrum and Milk
The aim of the present paper is to review the differences in chemical composition between colostrum and milk in cows. The concentrations of many nutrients (proteins, vitamins, minerals etc.) and biologically active substances (immunoglobulins, enzymes, hormones, growth factors etc.) are many times higher in colostrum than in milk. A special attention is given to insulin-like growth factors (IGF...
